This paper presents a method to realize floating inductance simulator using Operational Transconductance Amplifiers (OTAs). Both positive and negative floating inductances can be achieved without changing the circuit topology. The realization method is based on the use of commercially available OTAs and a grounded capacitor. The proposed circuit is attractive in terms of simple configuration an...
Nonlinear interactions among incident wave, tank-sloshing and freely floating body coupled motion are investigated. The fully nonlinear sloshing and body-surface nonlinear free surface hydrodynamics is simulated using a non-uniform rational B-spline higher-order panel method (NURBS) in time domain based on the potential theory. A robust and stable improved iterative procedure, iterative semi-im...
Low voltage (LV) analog circuit design techniques are addressed in this tutorial. In particular, (i) technology considerations; (ii) transistor model capable to provide performance and power tradeoffs; (iii) low voltage implementation techniques capable to reduce the power supply requirements, such as bulk-driven, floating-gate, and self-cascode MOSFETs; (iv) basic LV building blocks; (v) multi...
We present the numerical behavior of a projection method for convex minimization problems which was studied by Cegielski [1]. The method is a modification of the Polyak subgradient projection method [6] and of variable target value subgradient method of Kim, Ahn and Cho [2]. In each iteration of the method an obtuse cone is constructed. The obtuse cone is generated by a linearly independent sys...
PURPOSE Retinal cones have wave-length-specific visual pigments. To identify subclasses of cones, opsin-specific antibodies were previously established for the immunohistochemical studies of frozen sections. In this study, we produced retinal cone antibodies and examined (1) the specificity of these antibodies with Western blot analysis, (2) the application of these antibodies to paraffin-embed...
Technological advances have made FPGAs an attractive platform for the acceleration of complex scientific applications. These applications demand high performance and highprecision floating point arithmetic. In this paper, we present a design for calculating the Lennard-Jones potential and force as is done in molecular dynamics simulations. This architecture employs IEEE 754 double precision flo...
A computational study of partial cavitation over axisymmetric bodies is presented using two numerical methods. The first method is based on the VOF technique where transient 2D Navier-Stokes equations are solved along with an equation to track the cavity interface. Next, the steady boundary element method (BEM) based on potential flow theory is presented. The results of the two methods for a di...
A novel method was developed for determination of trace amounts of lead in water and food samples. Solidified floating organic drop microextraction was used to preconcentrate the lead ion. After the analyte was complexed with 1-(2-pyridylazo)-2-naphthol, undecanol and acetonitrile were added as extraction and dispersive solvent, respectively. Variables such as pH, volumes of extraction and disp...
Horses, like other ungulates, are active in the day, at dusk, dawn, and night; and, they have eyes designed to have both high sensitivity for vision in dim light and good visual acuity under higher light levels (Walls, 1942). Typically, daytime activity is associated with the presence of multiple cone classes and color-vision capacity (Jacobs, 1993). Previous studies in other ungulates, such as...
the objective of the present investigation was to design a sustained release floating microcapsules of theophylline using two polymers of different permeability characteristics; eudragit rl 100 (eu rl) and cellulose acetate butyrate (cab) using the oil-in-oil emulsion solvent evaporation method. polymers were used separately and in combination to prepare different microcapsules. the effect of d...
